The lovebirds have yet to confirm their relationship but while in Hawaii, they were spotted walking with their hands around each other on the beach.

According to E! News, the stars 'could not keep their hands off one another' during Comic Con 2017 over the summer.

'Since the show began, people have wanted Lili and I to be together,' Cole said about his relationship in an interview with Entertainment Weekly in September.

Adding: 'It’s very pleasing that people talk about Lili and I in that way because it means that we’re resonating so strongly from our character perspective that people really want that to be true.'

Cole concluded to EW: 'I think as professional actors we can pat ourselves on the back for that and go, "This was a success." It was such a success that people want to see it in real life.'
